摘　　要：本文提出了一种适用于高压下及低沸点物质液相粘度的测量方法—倾斜管式粘度测量方法,并设计和搭建了粘度测量系统。采用粘度测量系统标定的标准物质—纯水,通过测量其运动粘度,对该测量系统进行了检测。结果显示,该测量系统的相对偏差绝对平均值为0．65%,验证了该方法原理的正确性及测量系统的准确性。此外,测量了R134a饱和液体的运动粘度,进一步检测了该粘度测量系统。In this paper, we provide a method which can be used to measure the viscosity coefficient of the liquid under high-pressure condition and low-boil substances using inclined tube, and measurement system was designed and constructed. The kinematic viscosity coefficients of pure water which is the standard substance to calibrate viscosity measurement system were measured to verify the accuracy and reliability of the experimental system. The measurement results show that the absolute average of relative deviations is 0.65%. Then the kinematic viscosity coefficients of the saturated liquid of the low-boil substance, R134a were also measured to detect the measurement system.
